General Information
Installation
CAUTION
The Typical Installations in Fig. 2 are only guides
for selecting and installing system components.
Contact your Graco distributor for assistance in
planning a system to suit your needs.
Always use Genuine Graco Parts and Accessories.
Use a compatible, liquid thread sealant on all male
threads. Tighten all connections firmly to avoid air
or fluid leaks.
Tightening Threaded Fasteners Before
First Use
Before using the pump for the first time, check and
retorque all external fasteners. See Torque Se-
quence, page 29. After the first day of operation,
retorque the fasteners. Although pump use varies, a
general guideline is to retorque fasteners every two
months.
Safe Operating Temperatures
Minimum (all pumps): 40 F (4 C)
Maximum
Acetal: 180 F (82 C)
Polypropylene: 150 F (66 C)
Aluminum, stainless steel, PVDF: 225 F (107 C)
These temperatures are based upon mechanical stress
only and may be significantly altered by pumping certain
chemicals. Consult engineering guides for chemical compatibilities and temperature limits, or contact your Graco
distributor.
Mountings
These pumps can be used in a variety of installa-
tions. Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as
well as the stress caused during operation.
Fig. 2 shows some installation examples. On all
installations, mount the pump using screws and
nuts.
Pumping High-Density Fluids
High density fluids may prevent the lighter non-metallic
check valve balls from seating properly, which reduces
pump performance significantly. Stainless steel balls
should be used for such applications.
Toxic Fluid Hazard

Installation
Air Line
WARNING
A bleed-type master air valve (B) is required in your
system to relieve air trapped between this valve
and the pump. See Fig. 2. Trapped air can cause
the pump to cycle unexpectedly, which could result
in serious injury, including splashing in the eyes or
on the skin, injury from moving parts, or contamination from hazardous fluids.
CAUTION
The pump exhaust air may contain contaminants.
Ventilate to a remote area if the contaminants could
affect your fluid supply. Read Air Exhaust Ventila-
tion on page 6.
1. Install the air line accessories as shown in Fig. 2.
Mount these accessories on the wall or on a
bracket. Be sure the air line supplying the accessories is electrically conductive.
a. The fluid pressure can be controlled in either
of two ways. To control it on the air side, install
an air regulator (G). To control it on the fluid
side, install a fluid regulator (J) near the pump
fluid outlet (see Fig. 2).
b. Locate one bleed-type master air valve (B)
close to the pump and use it to relieve trapped
air. Read the WARNING above. Locate the
other master air valve (E) upstream from all air
line accessories and use it to isolate them
during cleaning and repair.
Installation of Remote Pilot Air Lines
1. Refer to Parts Drawings. Connect air line to pump
as in preceding steps.
2. Connect 1/4 in. O.D. tubing to push type connectors (16) on underside of pump.
NOTE: by replacing the push type connectors, other
sizes or types of fittings may be used. The new fittings
will require 1/8 in. npt threads.
3. Connect remaining ends of tubes to external air
signal, such as Graco’s Cycleflo (P/N 195264) or
Cycleflo II (P/N195265) controllers.
NOTE: the air pressure at the connectors must be at
least 30% of the air pressure to the air motor for the
pump to operate.
Fluid Suction Line
If using a conductive (acetal) pump, use conductive
hoses. If using a non-conductive pump, ground the
fluid system. Read Grounding on page 8. The
fluid inlet port is 1/2 in. or 3/4 in.
At inlet fluid pressures greater than 15 psi
(0.1 MPa, 1 bar), diaphragm life will be shortened.
Fluid Outlet Line
WARNING
A fluid drain valve (H) is required in your system to
relieve pressure in the hose if it is plugged. See
Fig. 2. The drain valve reduces the risk of serious
injury, including splashing in the eyes or on the
skin, or contamination from hazardous fluids when
relieving pressure. Install the valve close to the
pump fluid outlet.
c. The air line filter (F) removes harmful dirt and
moisture from the compressed air supply.
2. Install an electrically conductive, flexible air hose
(C) between the accessories and the 1/4 npt(f)
pump air inlet. Use a minimum 1/4 in. (6.3 mm) ID
air hose. Screw an air line quick disconnect coupler (D) onto the end of the air hose (C), and
screw the mating fitting into the pump air inlet
snugly. Do not connect the coupler (D) to the fitting
yet.
1. Use electrically conductive fluid hoses (K). The
pump fluid outlet is 1/2 in. or 3/4 in. Screw the fluid
fitting into the pump outlet snugly. Do not over-
tighten.
2. Install a fluid regulator (J) at the pump fluid outlet
to control fluid pressure, if desired (see Fig. 2).
See Air Line, step 1a, for another method of
controlling pressure.
3. Install a fluid drain valve (H) near the fluid outlet.
Read the WARNING above.
5308981
Installation
Fluid Pressure Relief Valve
CAUTION
Some systems may require installation of a pressure
relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose.
See Fig. 1.
Thermal expansion of fluid in the outlet line can
cause overpressurization. This can occur when using
long fluid lines exposed to sunlight or ambient heat,
or when pumping from a cool to a warm area (for
example, from an underground tank).
Overpressurization can also occur if the Husky pump
is being used to feed fluid to a piston pump, and the
intake valve of the piston pump does not close,
causing fluid to back up in the outlet line.

Air Exhaust Ventilation
Read Toxic Fluid Hazard on
page 3.
Read Fire and Explosion
Hazard on page 3.
Be sure the system is properly ventilated for your
type of installation. You must vent the exhaust to a
safe place, away from people, animals, food handling areas, and all sources of ignition when pumping
flammable or hazardous fluids.
Diaphragm failure will cause the fluid being pumped
to exhaust with the air. Place an appropriate container at the end of the air exhaust line to catch the
fluid. See Fig. 2 .
The air exhaust port is 3/8 npt(f). Do not restrict the air
exhaust port. Excessive exhaust restriction can cause
erratic pump operation.
Fig. 1
See Venting Exhaust Air in Fig. 2. Exhaust to a
remote location as follows:
1
2
9073A
1. Remove the muffler (W) from the pump air exhaust
port.
2. Install an electrically conductive air exhaust hose
(X) and connect the muffler to the other end of the
hose. The minimum size for the air exhaust hose
is 3/8 in. (10 mm) ID. If a hose longer than 15 ft
(4.57 m) is required, use a larger diameter hose.
Avoid sharp bends or kinks in the hose.
3. Place a container (Z) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures.
See Fig. 2.

Grounding
WARNING
FIRE AND EXPLOSION HAZARD
This pump must be grounded. Before
operating the pump, ground the system
as explained below. Also read the sec-
tion Fire and Explosion Hazard on page 3.
The acetal Husky 515 pump contains stainless
steel fibers, which makes the wetted parts conductive. Attaching the ground wire to the grounding
screw (106) grounds the wetted parts. See
grounding screw on page 25.
The metal Husky 716 pumps have a grounding
strip connecting the vee clamps (109). Attach a
ground wire to the grounding strip with the screw,
lockwasher, and nut as shown in the Grounding
Detail on page 27.
The polypropylene and PVDF Husky 515 pumps
are not conductive.
When pumping conductive flammable fluids, al-
ways ground the entire fluid system by making
sure the fluid system has an electrical path to a
true earth ground (see Fig. 3). Never use a polypropylene or PVDF pump with non-conductive
flammable fluids as specified by your local fire
protection code.
US Code (NFPA 77 Static Electricity) recommends
a conductivity greater than 50 x 10
ter (mhos/meter) over your operating temperature
range to reduce the hazard of fire. Consult your
fluid supplier to determine the conductivity or
resistivity of your fluid. The resistivity must be less
than 2 x 1012 ohm-centimeters.
To reduce the risk of static sparking, ground the pump
and all other equipment used or located in the pumping
area. Check your local electrical code for detailed
grounding instructions for your area and type of equipment.
–12
Siemans/me-
Ground all of this equipment:
Pump: The metal pump has a grounding strip in
front of the center housing. The acetal pump has a
grounding screw on the top manifold. Connect the
non-clamp end of the ground wire to the grounding
strip or grounding screw, and connect the clamp
end of the ground wire to a true earth ground. To
order a ground wire and clamp, order Part No.
222011.
Air and fluid hoses: Use only electrically conductive
hoses.
Air compressor: Follow the manufacturer’s recom-
mendations.
Solvent pails used when flushing: Follow the local
code. Use only grounded metal pails, which are
conductive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which
interrupts the grounding continuity.
Fluid supply container: Follow the local code.

Operation
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
The equipment stays pressurized until pressure is
manually relieved. To reduce the risk of serious
injury from pressurized fluid, accidental spray, or
splashing fluid, follow this procedure whenever you
Are instructed to relieve pressure
Stop pumping
Check, clean, or service any system equipment
Install or clean fluid nozzles
1. Shut off the air to the pump.
2. Open the dispensing valve, if used.
3. Open the fluid drain valve to relieve all fluid pressure, and have a container ready to catch the
drainage.
Flush Pump Before First Use
The pump was tested with water. Prior to first use,
flush the pump thoroughly with a compatible solvent.
Reactor feed pumps, part numbers 246484, 246485,
and 257447, were tested with lightweight oil, which is
left in the fluid passages. To avoid contaminating your
fluid with oil, flush the pump with a compatible solvent
before using the equipment. Follow the steps under
Starting and Adjusting Pump.
Starting and Adjusting Pump
1.
Read Toxic Fluid Hazard
on page 3.
5. Place the suction tube (if used) in the fluid to be
pumped.
NOTE: If the inlet fluid pressure to the pump is more
than 25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in inefficient
pump operation.
6. Place the end of the fluid hose (K) into an appropriate container.
7. Close the fluid drain valve (H).
8. With the pump air regulator (G) closed, open all
bleed-type master air valves (B, E).
9. If the fluid hose has a dispensing device, hold it
open while continuing with the following step.
Slowly open the air regulator (G) until the pump
starts to cycle. Allow the pump to cycle slowly until
all air is pushed out of the lines and the pump is
primed.
If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses. Close the
air regulator. Remove the suction tube from the
solvent and place it in the fluid to be pumped.
Operation of Remote Piloted Pumps
1. Fig. 2 and Parts Drawings. Follow preceding steps
1 through 8 of Starting and Adjusting Pump.
2. Open air regulator (G).
WARNING
The pump may cycle once before the external signal is applied. Injury is possible. If pump cycles,
wait until end before proceeding.
2.
3.
4. Check all fittings to be sure they are tight. Use a
compatible liquid thread sealant on all male
threads. Tighten the fluid inlet and outlet fittings
snugly. Do not overtighten the fittings into the
pump.
10 308981
If lifting the pump, follow the Pressure Relief Procedure above.
Be sure the pump is
properly grounded.
Read Fire and
Explosion Hazard
on page 3.
3. Pump will operate when air pressure is alternately
applied to push type connectors (16).
NOTE: Leaving air pressure applied to the air motor for
extended periods when the pump is not running may
shorten the diaphragm life. Using a 3–way solenoid
valve to automatically relieve the pressure on the air
motor when the metering cycle is complete prevents
this from occurring.
Pump Shutdown
At the end of the work shift, relieve
the pressure as described in Pressure Relief Procedure at left.
Maintenance
Lubrication
The air valve is lubricated at the factory to operate
without additional lubrication. If you want to provide
additional lubrication, remove the hose from the pump
air inlet and add two drops of machine oil to the air
inlet every 500 hours of operation or every month.
CAUTION
Do not over-lubricate the pump. Oil is exhausted
through the muffler, which could contaminate your
fluid supply or other equipment. Excessive lubrication
can also cause the pump to malfunction.
Flushing and Storage
Flush the pump to prevent the fluid you are pumping
from drying or freezing in the pump and damaging it.
Use a compatible solvent.
Always flush the pump and relieve the pressure
before you store it for any length of time.
Read Pressure Relief Procedure
on page 10.
Tightening Threaded Connections
Before each use, check all hoses for wear or damage
and replace as necessary. Check to be sure all
threaded connections are tight and leak-free.
Check fasteners. Tighten or retorque as necessary.
Although pump use varies, a general guideline is to
retorque fasteners every two months. See Torque
Sequence, page 29.
Preventive Maintenance Schedule
Establish a preventive maintenance schedule, based
on the pump’s service history. This is especially important for prevention of spills or leakage due to diaphragm failure.
